使用RAPD分析辨别印度半岛的五种结鱼(英文)

动物学报 2007年第4期53卷 725-732页

用RAPD分析研究了结鱼种组(黄鳍结鱼Tor putitora,结鱼Tor tor,库德里结鱼Tor khudree,Tor mosalmahanadicus和墨脱四■魮Neolissochilus hexagonolepis)5个物种的遗传关系。在所测试的69个随机引物中,11个引物能够在所有5个物种中扩增出稳定的条带。RAPD带型显示,综合使用这些RAPD标记能够区分这5个物种,但Tor mosal mahanadicus和黄鳍结鱼享有相似的带型。UPGMA分析揭示出3个独特的分支,第一支由黄鳍结鱼、Tor mosal mahanadicus和结鱼组成,第二支是库德里结鱼,第三支是墨脱四■魮。Tor mosal mahanadicus的分类地位在不同学者间存在分歧,被认为是库德里结鱼或结鱼的亚种,但我们的结果表明,相对而言,Mahanadi河中的Tor mosal mahanadicus与黄鳍结鱼的进化关系更近,因此有必要对其系统分类地位进行重新评估。
